Max Operating Depth (ppO2) Calculator

Oxygen can become toxic when breathed at high partial pressures. This calculator can be used to find the maximum operating depth at the defined partial pressure of oxygen (ppO2) with various percentages of oxygen. Just enter values for “Oxygen Mix” and “Partial Pressure” and hit “Compute MOD”

Oxygen Mix(O2%) – [1=100% or 0.21=21% etc]

Partial Pressure (ppO2) – [1.2 – 1.8] bar

Max Operating Depth(MOD) is: Metres.
